Upper Long - November 9, Secchi 5.70 m (18.7 ft). Fully mixed

Lower Long - November 9, Secchi 5.50 m (18.0 ft). Still stratified below 20 meters and anoxic below 24m.

So far in 2025 that's 17 sampling visits to Great Pond and 16 to Long Pond. We have another visit planned to lower Long coming up next week, and once it's fully mixed that will be it for Long Pond for the season. We have one more visit to Great Pond site 1 scheduled for early December as part of a collaborative NSF (National Science Foundation) project. We have to sample for that project once a month for 3 years straight (including December through April!) so we may be reaching out to schedule a ride on the air boat sometime soon.
